"Expanding Views of Africa" includes over 200 works, from 6,000-year-old Egyptian pottery to 19th-century Nguni beadwork to contemporary sculptures, like this Zambian face mask from 1980 made with wood, beads and plastic leaves pictured here.

We follow unsubtitled conversations in Nguni and assume we know what is said because of what is going on and because we've seen similar scenes in hundreds of other movies and TV shows but do we really know?
